Trees Make Antifreeze

first_imgThe chill of this spring hasn’t been good for many trees. Several freezes separated bywarm weather have caused major damage.Your oak may produce no acorns this year because the cold has killed all the femaleflowers.Trees can adjust to freezes, but these changes depend on the tree’s health, how muchfood it has stored and how fast temperatures change.For a tree, cold weather survival can be costly and disruptive, leading to stress andtissue death.Many trees can survive extreme cold. A northern willow holds the record for survival atminus 320 degrees Fahrenheit in a laboratory.Trees need time to prepare for freezes. Rapid change from warm to cold can damage themost hardy tree.If given time to adjust, a live oak (Georgia’s state tree) can survive to minus 18degrees. Southern magnolia and longleaf pine can survive to minus 50, sweet gum to minus20 and American elm to minus 55.When tree tissues get this cold or colder, they’re severely damaged. The parts a springfreeze will damage most are the growing areas at shoot tips and along twigs.Flower buds are extremely sensitive to cold. On one tree, flower buds may be 20 to 30degrees more sensitive than leaf buds.Roots are tender, too. They can’t adjust well to freezes once they’re growing. Colddamages leaves, if present, along the main veins and connection to the tree.The living tissue right behind a bud, connecting it with the twig, is highlysusceptible, too. It’s small, active, unprotected and exposed.The water-carrying tissues, which are dead when functional, aren’t affected. This leadsto what is called false, or dead, blooming in some trees. The blooms come out but quicklywither because connections to the living tree have been killed.Trees make a natural antifreeze to survive freezes. They do this in two stages.The first requires a gentle cooling-down to below 55 but not to freezing. The treestarts to gather sugars and break down stored starches.As the weather chills over a few days, trees start to change their living membranes tomaintain a liquid, cold-temperature form.Trees easily damaged by cold usually can’t modify their membranes, which becomeimpermeable solids when cold and suffocate the cells.Stage two happens below freezing. Trees use collected sugars and proteins to bind waterinside living cells and prevent ice crystals from forming.Between the cells, ice can form and pull water from the cells. If too much ice forms,new or sensitive tissues are mangled.Across the range of a tree species are usually many climatic races. Each has developedin areas with unique fall and spring temperature patterns.Moving Southern races farther north can damage trees. A rule-of-thumb is to beware ofmoving native trees more than 100 miles south-to-north or 300 miles east-to-west.Southern trees moved only a few hundred miles north can have many problems:* They don’t develop enough resistance to cold damage.* They aren’t fast enough in developing resistance in the fall.* They come out too early in the spring.* And they’re killed by extreme freezes that happen every few years.Northern tree races won’t grow early enough in spring and will shut down too early infall to stay healthy farther south.Trees are tuned to their environment. They make all the materials and growth responsesthey need to survive and thrive in normal weather. But extreme and unseasonal cold canstress them badly.Keeping trees healthy is one of the best things you can do to keep down the stress ofhard freezes.last_img read more

Zamalek boss escapes assassination attempt

first_imgZamalek chairman Mortada Mansour has survived an alleged assassination attempt in the early hours of Sunday morning, reported Ahramonline.According to Mansour’s son, Ahmed, his father was attacked by unidentified gunmen who opened fire as he was walking out of the club’s headquarters.Mansour was unharmed but two club’s staffs were injured in the attack.The incident occurred as the relationship between Zamalek management and hard core fans “Ultras White Knights” have been deteriorating for weeks over several issues including the sacking of former coach Mido.And Mansour was quick to point the finger at the group.“Ultras White Knights is not a football fan group but a terrorist organisation. They tried to kill me and two people were injured,” he told the media following the incident. “I won’t give up my right. All Egyptian media must boycott them and I will take legal actions to ban the Ultras groups.”“We won’t deal with Ultras again.

John Calipari Goes On Twitter Rant Following Criticism For Saying Kentucky’s Goal Was To Get 8 Players Drafted

first_imgJohn Calipari tweets about his draft goal.Twitter/@UKCoachCalpariOn Wednesday, John Calipari rubbed some people the wrong way when he said Kentucky’s goal this past season was to get eight players drafted, not win the national championship. Calipari, 56, is as big of a players-first coach as there is in sports, so his comments weren’t really that surprising. But, at the same time, it’s not surprising that people were upset with his statement. The Wildcats’ coach went on somewhat of a Twitter rant this afternoon, addressing his critics. I hate to drive you traditionalists crazy, but I’ll say it again: our goal at the beginning of the season was to have eight players drafted.— John Calipari (@UKCoachCalipari) May 21, 2015I’ll be honest with you, at the time I may have said nine. My point when I said that was to have them all eat.— John Calipari (@UKCoachCalipari) May 21, 2015When they asked how we do it, I told them to do this you will have to be a selfless team, share & do historic things on the court. They did.— John Calipari (@UKCoachCalipari) May 21, 2015If Alex doesn’t get hurt, 8 are drafted. We fell short of a national title but this season was not disappointing to me. Have a great day!— John Calipari (@UKCoachCalipari) May 21, 2015Whether you agree with him or not, you’ve got to respect Calipari for always speaking his mind.last_img read more
